Offers information, objectives, possible student outcomes, a student quiz on electronic imaging technologies. Discusses the evolution of the process from the development of the camera in the 1550s to virtual reality, infrared imaging, and laserdisks. (JOW)

Describes the use of a laser pointer to measure the speed of light by incorporating the phase delay between a modulated split beam of light. (JRH)

Provides instructions for preparing, processing, and viewing single-beam reflection holograms in science classrooms. Indicates that the process is simple to demonstrate and moderate in cost. A description of the required equipment (optics table, laser, mirrors, lens, filmholder/plateholder, recording materials, and darkroom chemicals/equipment) is…

Describes simple inexpensive modifications to existing equipment that facilitate the computerization of interference and diffraction experiments done in introductory laboratory courses. (JRH)

A procedure for measuring the speed of light using the assumption that the frequency of light remains unchanged as it moves from one medium to another is presented. A laser with a known wavelength and frequency in air was used as a light source. (KR)

Describes various methods of rendering visible the paths followed by a laser beam for direct viewing or for photographic purposes. (Author/GS)

Describes the theory and application of an atomic fountain which pushes the atoms by laser pulses. Discusses the applications in measuring atomic properties and in building an atomic clock. (YP)

This compendium of interdisciplinary learning activities is designed to assist technology education instructors who are conducting an introductory secondary-level course in communication technology. The 12 activities, which are sequenced from introductory, low-cost activities to more advanced and more involved activities, deal with the following…

Construction of a laboratory area suitable for laser experiments and the creation of holograms is described. (CP)

Describes the apparatus and procedures for conducting a simple speed of light experiment in an average laboratory using a laser source, a rotating mirror, and an oscilloscope. (SL)

Several activities that can be used to teach the science of bar codes are presented. Examples of simple codes are provided. The use of bar code scanners is discussed. (CW)

Presents a problem in which the incorrect application of the Law of Sines leads to an erroneous solution. Demonstrates that the commission of this error by an ophthalmologist using laser trabeculoplasty could lead to patient injury. (MDH)

Outlines what a hologram is, the main types of holography, and how a simple system producing a white light reflection hologram can be set up in a school physics laboratory. Discusses the basic optics of the hologram and procedures and materials for making holograms in school. (YP)

Describes a homemade experimental chamber constructed to accurately measure the refractive index of a transparent liquid. (MDH)

Presents: (1) method for tuning sonometers with a VELA and sensing device; (2) computer simulation of two-dimensional gas diffusion; (3) inexpensive procedure for digitizing with better than 0.5mm precision (with program listing); and (4) a simple optical diffraction analogue apparatus for use with the laser.
